Abstract
A control device being a control device communicating with a controlled device to control the controlled device includes: a first memory to store first authentication information for authenticating the controlled device; a second memory to store second authentication information for making the controlled device authenticate itself; a determination unit to compare third authentication information sent from the controlled device for specifying the controlled device with the first authentication information; a calculator to perform calculation processing on the first authentication information or the third authentication information using the second authentication information to generate a calculated value; a transmitter to transmit, when the determination unit determines that the first authentication information and the third authentication information are the same, the calculated value to the controlled device; and a memory controller to update the first authentication information.
